Referring to FIG. 1, it shows a lamp network made of a plurality of ornamental lamps, and it comprises a main power-supply cable 13 and a plurality of lamp strings 12; each lamp string is connected with one socket of the main power -supply cable 13 by means of a connecting member 15. Each lamp string 12 includes an independent power-supply wire 18A and an independent Power-supply wire 18B to connect a plurality of sockets in series; the base surface 19 of every socket 14 in each lamp string 12 is mounted with a clasper 17, of which the lamp chute 44 is used for holding the power-supply wire 18B in place. In the network ornamental lamp 11, the upper part of each socket 14 has a fastening member 27 mounted around the bulb 16; the tail end of an arm plate 29 of the fastening member 27 has a hook hole 30 to be mated with a hook 46 of an arm plate 45 extended out of the clasper 17 so as to prevent the clasper 17 from luxating.
Referring to FIGS. 1 to 5, one end of each socket 14 in each lamp string 12 has a connector 15 to be mounted with a bulb 16, while the other end thereof has a guide chute for receiving power-supply wires 18. Both sides of the guide chute are furnished with two symmetrical flat surfaces 20 and two symmetrical curved surfaces 22 respectively so as to provide a socket-positioning surface 19 for mounting the clasper 17.
The clasper 17 to be mounted on the socket-positioning surface 19 of the socket 14 has an outer edge, which includes two symmetrical wide wall plates 41 and two symmetrical curved plates 42; the inside of the clasper 17 has a clamp sleeve 47 for mounting the socket-positioning surface 19 of the socket 14; both sides of clamp sleeve 47 are furnished with two symmetrical clamp chutes 44 respectively. One of the wide wall plate 41 A has a cutout 43, which can facilitate the power-supply wires 18 to be inserted into the clamp sleeve 47 before the clasper 17 being mounted on the socket-positioning surface 19 of the socket 14. Before the clasper 17 is mounted to the socket 14, the power-supply wires should be inserted into the clamp chute 44 first.
In order to prevent the clasper 17 being separated from the socket 14 unintentionally, the wide wall plate 41 B of the clasper 17 without cutout 43 is furnished with an arm plate 29 extended out of the top flat surface 35; the tail end of the arm plate 29 has a hook hole 30; the arm plate 29 is connected with the clasper 17 by means of a bendable thin plate 31 so as to provide the arm plate 29 with a bendable function. Between the hook hole 30 on the tail end of the arm plate 29 and the end of the bendable thin plate 31, there is a given length so as to facilitate the hook hole to mate with a hook 46 on the socket 14.
The hook 46 of the socket 14 is furnished on the cylindrical surface 33 of the flat surface 20 of socket 14, and is nearing the top flat 34 of the socket; the hook 46 faces upwards.
To make a lamp network with a plurality of lamp strings 12, the power-supply wire 18B between two adjacent sockets 14 of two adjacent lamp strings 12 should be inserted, through the cutout 43, into the clamp sleeve 47 of the clasper 17. When the clasper 17 is mounting on the socket-positioning surface 19 of the socket 14, the power-supply wires 18 should be inserted into the clamp chutes 44 on both sides of the clasper 17, i, e., on one side of the socket 14; then, a network of ornamental lamps 11 is completed. A hook 46 is furnished on the top flat 34 of the cylindrical surface 33, and it is to be mated with the hook hole 30 on the tail end of the arm plate 29 upon the plate 29 being bent with the bendable thin plate 31; then, the clasper 17 will not be separated from the socket upon the power-supply wires 18 being pulled unintentionally.
